rseek.org is a good place to start for locating functions. We might be better able to help if you'd told us where you got that code in the first place. On Tue, Nov 6, 2012 at 8:53 AM, yuyaxuan <309772486 at qq.com> wrote:
Hello guys, I am wondering that whether we have the function loc() in R package??? If so, which one should I install? For example, "locrow = loc(row!=0.0)" I met this in the code...I checked the code,, But I didn't find the self defined function..
@yuyaxuan <309772486 at qq.com> That code looks dangerous. I guessing it was written by an inexperienced R programmer and that 'loc' is a synonym for `which`. You should not be testing or equality of floating point numbers .... read the FAQ. I searched using findFn in the sos package, and could not find such a function, so my guess is that it was defined in the preceding code that you have not shown.
